VH-XXX - Before spreading speculation from the lack information you no doubt have, I suggest you refrain and get your facts straight. There is more to it than just money.
Also, If you're squabling over $25, you shouldn't be in aviation. The proceeds go to charity and you'll find most airports hit you with a landing fee. You're no different to any other paying patron walking through the front gates, unless you're part of the airshow.
